How do you know if your catalytic converter goes bad?
Other than the computer throwing a code, is there any way for you to tell if your catalytic converter is bad? The guy at the muffler shop told me that my catalytic converter is what caused too much back pressure and made my flex pipe after my exhaust manifold go bad on my truck and I want to make sure that I'm not being taken before I just go ahead and replace it. Thanks in advance!
